Data Memory Access Times
Figure 4-8.
This section describes the general access timing concepts for internal memory access. The
internal data SRAM access is performed in two clk
Figure 4-9.
The Atmel
It is organized as a separate data space, in which single bytes can be read and written. The
EEPROM has an endurance of at least 100,000 write/erase cycles in automotive range. The
access between the EEPROM and the CPU is described in the following, specifying the
EEPROM Address Registers, the EEPROM Data Register and the EEPROM Control
Register.
